Foerste states in the Botanical Gazette for 1892 that vas- 
cular strands are found beneath the usual position of the 
larger prickles of Xanthoxylum even when these are aborted. 
Specialized outgrowths from a plant member are sometimes 
distinguished under the name emergences, particularly when 
they contain vascular elements.
